Thanks for posting this. The only thing I am missing from my stirplate was the transformer and I had noticed that train transformers looked very similar to what I needed. Since I am clueless, it is good to have a confirmation.

Off to a hobby shop this weekend.

What needs to be understood here is that I'm pretty much clueless when it comes to the science of electronics.

Also, if you don't have a hard drive to spare, where do you get the magnets???
Google "rare earth magnets" and you will find more than a dozen places selling them on line... I think you can even get them on ebay for a few bucks.

As far as mounting the fan inside your project box, that's what most guys do. Yuri has a great set up if you want to get fancy.

Bit of an update here,... I started doing a bit more reading on starters. Come to find out I need about twice as much starter than I can produce (I put out 400 ml / batch)

Has anyone split a starter between to flasks and alternated them on the stirplate? I'm thinking 24 hrs on original then split the batch into two 400 ml batches and give em 8 hrs on 8 hrs off?

Am I risking to much infection?

As long as everything is nice and clean and you keep an airlock on the flask while it's off the stirplate you should be able to make it work. I'd be a little concerned about not getting O2 and the yeast going anaerobic more than infection.

Any reason you can't just get a flask twice the size of your current flask? Also, since you have such an inexpensive stirplate why not just make another?

You can get a 1 gal jug from your LHBS for about $5.00. heck of a lot cheaper than an Erlenmeyer flask. The only drawback is that you can't boil your starter wort in it.

That's pretty much what I resigned myself to... I'll make up another.

I don't mean to steal this post, but I wonder if someone could use one of these http://www.helmangroup.com/nostalgia/default.asp?c=8&p=354 as a make-shift stir plate?

Any thoughts?

I'm totally making one of these. My brother in law just gave me a bum computer and I'm gonna gut it for the parts. Question though...I've never made a starter but have read about it. How long do you leave it on the stir plate? Should you oxiginate it?

jmsullivan: probably would require some internal re-wiring, and is probably costing you too much to begin with to boot .

Trodd: how long is a matter of method; many people wait 6-8 hrs. for the activity to maximize and then pitch the whole thing. Others (like me) fear the oxygenated wort, so we let it ferment out over 24 hrs, then put in the fridge for 30 minutes before decanting off the wort and pitching the slurry.
